Includes listings for all commercially available AHSS grades as well as grades under advanced stages of development.

AHSS grades under development

In addition to the “open for sales” grades listed in the tables below, SSAB is constantly developing new grades based on future needs of leading car OEMs and Tier1 suppliers.

Grades currently available for customer testing include:

  • Docol® HR800CP: new and improved, with 760 Mpa ultimate tensile strength
  • Docol® HR800CP+HER: now available with a guaranteed minimum hole expansion (+HER), typically 70%
  • Docol® HR800HE: typical HER of 100%, providing extreme local formability and high edge (HE) ductility
  • Docol® HR1000CP: target for trial material release is Q1 or Q2 of 2021.

Dual phase with high formability

Metal coated Docol® 600DH-GI and 800DH-GI are two of the steel grades now available and more are on the way.

A special heat treatment producing mainly two-phase structure makes Docol® 600DH-GI and 800DH-GI suitable where an improved formability is requested compared to conventional dual-phase steel grades with the same tensile strength level.

Press Hardening Steel (PHS)

For Press Hardening (PHS) Steel it is the forming process which sets the final characteristics on the material. Forming at high temperatures facilitates complex structures as the martensitic microstructure is developed after press hardening. This material has a limitation in welding properties.

Complex Phase (CP) steels

Complex Phase (CP) steels have higher yield strength and lower work hardening effect, compared to DP steels for same strength level. The CP steels have good fatigue properties when it comes to low cycle fatigue. Compared to DP, the CP steels offer better flanging and ISO hole expansion performance and these steels are suitable for applications where high strength, good bendability and stretch-flange ability is required.

Dual Phase (DP) steels

For Dual Phase (DP) steels there is a big difference in yield and tensile strength in un-deformed areas. The work hardening in forming is very strong. DP steels have good formability compared to its strength but are limited in hole expansion. With its lean composition these steels are easy to weld but sensitive to heat treatment (> 200 °C).

High Strength Low Alloy (HSLA) steels

High Strength Low Alloy (HSLA) steels have a typically small difference between yield strength and tensile strength (<100 MPa). They, therefore, offer excellent bendability. With little pearlite and no other hard phases they also have better fine blanking properties compared to DP steels and due to lean composition they are very easy to weld.

Ferrite-Bainite

Ferrite-Bainite (FB) steels have mechanical properties that are similar to Complex Phase (CP) steels but with a higher gap between yield and tensile strength. FB steels are characterized by good bendability and excellent stretch-flange ability. They are best suited for parts with stretched flanges such as chassis components in cars.
